The town of Ribchester is an area of very high archaeological potential. It is the site of the Roman Fort of Bremetennacum and associated extra-mural settlement, dating from the first century AD. The fort lies on the south-west edge of town and is protected as a Scheduled Monument (SM 14255). The site is positioned to the north-east of the Roman bath house and may lie on the edge of the vicus or civilian settlement area. Blackburn Road, on which The Limes is situated is thought to overlie a Roman road leading east from Ribchester Fort. Oxford Archaeology North (OA North) undertook the watching brief in January 2005. The foundation trenches were excavated to a maximum depth of 1.35m, revealing topsoil between 0.2-0.5m in depth overlying natural sandy subsoil. The watching brief did not reveal any finds or features of archaeological significance.

The watching brief was carried out by Kathryn Blythe, who also wrote the report and produced the drawings. The project was managed by Emily Mercer, who also edited the report along with Alan Lupton.

INTRODUCTION 1.1 CIRCUMSTANCES OF THE PROJECT 1.1.1 Mrs Pauline Howarth submitted a planning application (ref 3/04/1023/p) to Lancashire County Council for a garage and extension to the domestic dwelling known as The Limes, Blackburn Road, Ribchester (Fig 1) (NGR SD 65861 35410). 1.1.2 The Limes is situated on Blackburn Road that is thought to overlie a Roman road leading east from Bremetennacum, Ribchester Fort. It is also positioned to the north-east of the Roman bath house and may lie on the edge of the vicus or civilian settlement area. Due to the archaeological potential of the site LCAS recommended that a watching brief should be undertaken during groundworks on the site. In accordance with the brief, a project design (Appendix 1) was produced by Oxford Archaeology North (OA North) outlining the proposals for the required work which was undertaken during January 2005. 1.1.3 This report sets out the results of the watching brief in the form of a short document. This outlines the historical background for the site and the results of the watching brief.

METHODOLOGY 2.1 PROJECT DESIGN 2.1.1 A project design (Appendix 1) was submitted by OA North, in response to a request by the client, for an archaeological watching brief. The project design was adhered to in full, and the work was consistent with the relevant standards and procedures of the Institute of Field Archaeologists, and generally accepted best practice. 2.2 WATCHING BRIEF 2.2.1 A programme of field observation was undertaken during the groundworks to record the location, extent and character of any surviving archaeological features and deposits revealed during the ground disturbance. 2.2.2 The foundation trenches for the extension and garage were undertaken using a mechanical excavator with a toothless ditching bucket under constant archaeological supervision. A monochrome and colour slide photographic record was maintained throughout. 2.3 ARCHIVE 2.3.1 A full archive of the project has been produced to a professional standard in accordance with current English Heritage guidelines (English Heritage 1991). The archive comprises all the information gathered during the course of the project and will be deposited at Lancashire County Record Office (Preston) on completion of the project. In addition, a copy of the report will be archived with the Lancashire County SMR in Preston.

BACKGROUND 3.1 LOCATION, GEOLOGY AND TOPOGRAPHY 3.1.1 Site Location: The Limes (NGR SD 658610 35410) is located approximately 600m from Ribchester, on Blackburn Road which heads east out of the town, and 250m to the west of the River Ribble (Fig 1). The town of Ribchester is in central Lancashire, roughly mid-way between the central Pennine uplands and the Irish Sea. 3.1.2 Geology: the solid geology around Ribchester is dominated by Sabden shales of the Millstone Grit Group masked by thick (up to 50m to rockhead) boulder clay deposits (Aitkenhead et al 1992). Ribchester town and the fort are thought to stand on deposits of a second terrace of the
